You are implementing an ASP.NET AJAX page that contains two div elements. You need to ensure that the
content of each div element can be refreshed individually, without requiring a page refresh.
What should you do?

• A. Add two forms to the page. Add a script manager and an update panel to each form. Add a content template to each update panel, and move each div element into a content template.
• B. Add a form and two update panels to the page. Add two script managers to the form, one for each update panel. Add a content template to each update panel, and move each div element into a content template.
• C. Add two forms to the page. Add a script manager and an update panel to each form. Add a content template to each update panel, and move each div element into a content template.
• D. Add a form and two update panels to the page. Add a script manager to the form. Add a content template to each update panel, and move a div element into each content template.

You are designing a user input form that is part of an ASP.NET Web Forms application. You need to ensure that users cannot attack the Web server by submitting invalid data. Which approach should you recommend?

• A. Write an onSubmit JavaScript handler that URL-encodes all data that is passed to the server.
• B. Write an OnClick method for the Submit button that rejects form submissions that contain invalid data.
• C. Write an onSubmit JavaScript handler that validates all form input.
• D. Install a certificate on the Web server, and force all Web traffic to use SSL.

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application.
The application contains the following code segment. (Line numbers are included for reference only.)
01 class DataAccessLayer
02 {
03 private static string connString;
04
05 ...
06 public static DataTable GetDataTable(string command){
07
08 ...
09 }
10 }
You need to define the connection life cycle of the DataAccessLayer class. You also need to ensure that
the application uses the minimum number of connections to the database.
What should you do?

• A. Insert the following code segment at line 04. private SqlConnection conn = new SqlConnection(connString); public void Open(){
  conn.Open();
  }
  public void Close(){
  conn.Close();
  }
• B. Insert the following code segment at line 04. private static SqlConnection conn = new SqlConnection(connString); public static void Open(){
  conn.Open();
  }
  public static void Close(){
  conn.Close();
  }
• C. Insert the following code segment at line 07. using (SqlConnection conn = new SqlConnection(connString)){
  conn.Open();
  }
• D. Replace line 01 with the following code segment. class DataAccessLayer : IDisposable Insert the following code segment to line 04. private SqlConnection conn = new SqlConnection(connString); public void Open(){
  conn.Open();
  }
  public void Dispose(){
  conn.Close();
  }

You use Microsoft Visual Studio 2010 and Microsoft. NET Framework 4 to create an application. The application connects to a Microsoft SQL Server database. You use Entity SQL of the ADO.NE Entity Framework to retrieve data from the database. You need to define a custom function in the conceptual model. You also need to ensure that the function calculates a value based on properties of the object. Which two XML element types should you use? (Each correct answer presents part of the solution. Choose two.)

• A. Dependent
• B. Association
• C. DefiningExpression
• D. Function
• E. FunctionImport

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. You
create stored procedures by using the following signatures:
"CREATE procedure [dbo].[Product_Insert](@name varchar(50),@price float)
"CREATE procedure [dbo].[Product_Update](@id int, @name varchar(50), @price float)
"CREATE procedure [dbo].[Product_Delete](@id int)
"CREATE procedure [dbo].[Order_Insert](@productId int, @quantity int)
"CREATE procedure [dbo].[Order_Update](@id int, @quantity int,@originalTimestamp timestamp) "CREATE procedure [dbo].[Order_Delete](@id int)
You create a Microsoft ADO.NET Entity Data Model (EDM) by using the Product and Order entities as shown in the exhibit. You need to map the Product and Order entities to the stored procedures. Which two procedures should you add to the @productId parameter? (Each correct answer presents part of the solution. Choose two.)

• A. Product_Delete
• B. Product_Update
• C. Order_Delete
• D. Order_Update
